The CRT-14 is the first tool in the industry to address complete carbon removal from the gas system of M-14 / M1A platform rifles. Previously the only options available to M-14 operators were drill bits, which can easily alter the dimensions of the gas system components. The CRT-14 is a professional tool specifically designed to remove the carbon from the very difficult-to-clean cavities of the M-14 / M1A gas system. The assurance of the dead-stop reamer design will prevent damage during cleaning.

The CRT-14 is made up of 2 parts. The flat wrench has a hex that fits the gas system plug, and the other-side has a circle with a flat to match the rear of the gas piston. This allows the user to effectively rotate the CRT-14 dead-stop reamers inside the deep cavities of the gas piston to ensure complete carbon removal. The CRT-14 has 3 specific dead-stop reamer ends to clean the two cavities of the gas piston and the gas system cross-hole, and the gas system plug.
